It is also possible to get alternating key values and value values by ... Dictionary keys can be individually deleted ... Python 2.7 and 3.x also support ...
Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})
Any existing mapping is overwritten. The arguments to this operation are the key and the value. Remove or delete remove a (,) pair from the collection, unmapping a given key from its value. The argument to this operation is the key. Lookup, find, or get find the value (if any) that is bound to a given key.
In computing, a hash table is a data structure that implements an associative array, also called a dictionary or simply map; an associative array is an abstract data type that maps keys to values. [2] A hash table uses a hash function to compute an index, also called a hash code, into an array of buckets or slots, from which the desired value ...
Associative array (or dictionary) of key and value pairs; can contain mixed types (keys and values), keys must be a hashable type {'key1': 1.0, 3: False} {} types.EllipsisType: immutable An ellipsis placeholder to be used as an index in NumPy arrays ... Ellipsis: float: immutable Double-precision floating-point number.

In computer science, a retrieval data structure, also known as static function, is a space-efficient dictionary-like data type composed of a collection of (key, value) pairs that allows the following operations: [1] Construction from a collection of (key, value) pairs
Since Cancer and Scorpio get along swimmingly as well. But Aquarius offers a refreshing contrast to Scorpio’s intensity and together, they bring out the best in both signs . 9.
